Multi-Channel Magnetic Resonance sounding system for direct detection of groundwater - down to 150m depth. Groundwater resources evaluation: Determination of water level and quality; Lateral extension of an aquifer layer; Selection of the best place to drill; Prediction of yield, after calibration.

PROMIS is a slingram HLEM system using a transmitter loop to produce a primary magnetic field, linked by a cable to a receiver sensor located at a given spacing from the transmitter; the system measures the three in-phase and out-of-phase components of the secondary magnetic field induced in the ground by conductive structures. The profile is carried out by measuring a set of frequencies at each station, and by moving both the transmitter and the receiver to the next station.

Elrec 2 is a two dipole Time Domain Induced Polarization receiver designed for deep resistivity sounding and high productivity surveys in mineral exploration. It has been designed for being both a user friendly and a very sensitive IP receiver. Elrec 2 measuring process has been optimized to provide the best possible accuracy in real field conditions.

The SYSCAL Pro Switch units use segments (seg) of multi-core cable which are reversible and interchangeable.

For instance, the SYSCAL Pro Switch 48 with 10m spacing has 4 segments of cable a, b, c, d, with 12 electrodes each, for a total line length of 480m. The SYSCAL is placed in the middle of the line, between segments b and c. If the profile to measure is longer than the line length, a ROLL ALONG technique can be applied where, after a first set of readings with (a, b, c, d), segment a is placed after segment d to form a new (b, c, d, a) combination etc.

The SYSCAL JUNIOR Switch-48 is an all-in-one multi node resistivity imaging system. It features an internal switching board for 48 electrodes and an internal 200W power source. The output current is automatically adjusted (automatic ranging) to optimize the input voltage values and ensure the best measurement quality. The system is designed to automatically perform pre-defined sets of resistivity measurements with roll-along capability. Four multi-core cables with 12 electrodes takeout each are connected on the back of the resistivity meter.
